Several arylacetaldehydes 5 were synthesized in moderate yields via Heck reaction of acrylamide (1) with substituted iodobenzenes 2 in the presence of the polymeric catalyst -phenyl-(1,10-phenanthroline)-palladium(0) [-ph-phen.Pd(0)] followed by Hofmann reaction and subsequent hydrolysis.
Structure-activity relationship studies on a series of Boc-indole derivatives as LXR agonists are described. Compound 1 was identified as an LXR agonist through structure-based virtual screening followed by high-throughput gene profiling. Replacement of the indan linker portion in 1 with an open-chain linker resulted in compounds with similar or improved in vitro potency and cellular functional activity

A simple and green method of visible light driven photocatalytic E to Zisomerization of alkenes has been developed. A variety of (Z)-alkenes can be prepared in the presence of visible light, without any additional photocatalyst. This protocol features photocatalyst-free conditions, which are mild, tolerant, and operationally simple, and is easy to implement.
Copper(II)-Catalyzed Reactions of α-Keto Thioesters with Azides via C–C and C–S Bond Cleavages: Synthesis of <i>N</i>-Acylureas and Amides

Cu(II)-catalyzed reaction of α-keto thioesters with trimethylsilyl azide (TMSN3) proceeds with the transformation of the thioester group into urea through C–C and C–S bond cleavages, constituting a practical and straightforward synthesis of N-acylureas. When diphenyl phosphoryl azide (DPPA) is used instead as the azide source in an aqueous environment, primary amides are formed via substitution of
